DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the display device 1 is a humanoid robot that stands out even from a distance, and is provided on a base plate 3 provided with casters 2. The body of the robot is divided into a lower body 4 and an upper body 5 in a freely rotatable manner, and legs 6 provided on the lower body 4 are fixed to the base plate 3. The two arms 7 of the robot are swingably attached to the upper trunk 5, and a flag 8 is attached to each arm 7. Further, red and blue rotary indicator lamps 10 and 11 are attached to a head 9 provided at the upper end of the upper trunk 5.
[0008]
As shown in FIGS. 2 and 3, a support shaft 12 is planted at the center of the lower body 4, and this support shaft 12 is inserted into a bearing 13 provided at the center of the upper body 5. Is provided with a gear 14. A motor 15 is provided in the upper body 5, and a gear 16 provided on a rotation shaft of the motor 15 is engaged with the gear 14.
[0009]
As shown in FIGS. 4 and 5, a support shaft 17 is implanted in the upper body 5, and this support shaft 17 is inserted into a bearing 18 provided at the rear end portion of the arm 7. Pins 19 are implanted. A motor 20 is provided in the upper body 5, a disc 21 is provided on the rotating shaft of the motor 20, and a pin 22 is implanted on the edge of the disc 21. The pin 19 at the rear end of the arm 7 and the pin 22 at the edge of the disc 21 are connected by a crank 23.
[0010]
The red and blue rotating indicator lamps 10 and 11 provided on the robot head 9 have a reflecting mirror rotating around the fixed lamp, and are attached to the head of an emergency car or the exit of a parking lot. Commercially available rotating indicator lamps are used.
[0011]
Each of the above-described devices 10, 11, 15, and 20 is connected to a control device 24 provided in the upper trunk 5, and the control device 24 is connected to a commercial power source by an electric wire 25 and is activated by a switch 26. Yes.
[0012]
As shown in FIG. 7 , at the entrance Y of the gas station S, a first vehicle detector 27 that detects a vehicle traveling on the road R in front of the gas station S toward the gas station S is provided. At the outlet Z of the gas station S, a second vehicle detector 28 for detecting a vehicle leaving the gas station S is provided. These vehicle detectors 27 and 28 are connected to the control device 22 described above.
[0013]
Next, the operation will be described with reference to the flowchart of FIG. When the display device 1 is placed at the outlet Z of the gas station S, the electric wire 25 is connected to a commercial power source, and the switch 26 is turned on (ST1), an operation signal is output from the control device 24 to the motor 20 and the rotary indicator lamps 10 and 11. (ST2). The motor 20 is rotated by an operation signal from the control device 24, and the rotation of the motor 20 is transmitted to the arm 7 as a swinging motion via the disk 21 and the crank 23, and the flag 8 attached to the tip of the arm 7 is large. to be dumped. Then, the red and blue rotating indicator lamps 10 and 11 are actuated by the actuation signal from the control device 24, and the red and blue lights blink.
[0014]
As described above, when there is no vehicle leaving the gas station S, the display device 1 displays an advertisement on the vehicle traveling on the road R to enhance the function.
[0015]
There is a vehicle leaving the gas station S, and a vehicle detection signal is input from the second vehicle detector 28 to the control device 24 (ST3), and at this time, the vehicle is traveling on the road R toward the gas station S. When a vehicle detection signal is input from the first vehicle detector 27 to the control device 24 (ST4), an operation signal is output from the control device 24 to the motor 15 and an operation signal to the rotation indicator lamp 11 is output. Stops (ST5). The motor 15 is rotated forward by an operation signal from the control device 24, and the upper body 5 rotates when the gear 16 provided on the rotation shaft of the motor 15 meshes with the gear 14 provided on the lower body 4. Then, from the position facing the road R side to the position facing the exit Z side, it rotates by about 90 degrees and stops. Further, the operation signal from the control device 24 to the rotation indicator lamp 11 is stopped, the operation of the blue rotation indicator lamp 11 is stopped, and only the operation of the red rotation indicator lamp 10 is performed.
[0016]
As described above, when the vehicle leaves the gas station S, if there is a vehicle traveling on the road R in the direction of the gas station S, the display device 1 displays the stop and exits the gas station S. To ensure the safety of the car.
[0017]
When the vehicle passes in front of the gas station S and the vehicle detection signal disappears from the first vehicle detector 27 input to the control device 24 (ST6), an operation signal is sent from the control device 24 to the motor 15. It is output (ST7). The motor 15 reverses in response to an operation signal from the control device 24, and the upper body 5 rotates in the reverse direction. Then, from the position facing the exit Z side to the position facing the road R side, it rotates in the reverse direction by about 90 degrees and stops. As a result, the car leaves the gas station S.
[0018]
In this way, there is a car leaving the gas station S, and after a vehicle traveling toward the gas station S passes through the road R, the display device 1 displays the departure and displays a new road R. Is informed that there is a car leaving, and the safety of the car leaving the gas station S is ensured.
[0019]
When the vehicle leaves the gas station S and the vehicle detection signal disappears from the second vehicle detector 28 input to the control device 24 (ST8), an operation signal is output from the control device 24 to the blue rotation indicator lamp 11. (ST9). Then, the blue rotating indicator lamp 11 is actuated again, and the display device 1 becomes an advertising display.
[0020]
When there is a car leaving the gas station S and a vehicle detection signal is input from the second vehicle detector 28 to the control device 24 (ST3), the vehicle travels on the road R toward the gas station S. If there is no vehicle coming and no vehicle detection signal is input from the first vehicle detector 27 to the control device 24 (ST4), the control device 24 stops the operation signal to the rotation indicator lamp 11 (ST10).
[0021]
Thus, when the vehicle leaves the gas station S, if there is no vehicle traveling on the road R in the direction of the gas station S, the display device 1 immediately displays the departure and displays a new road. The vehicle that has traveled R is informed that there is a vehicle leaving, and the safety of the vehicle leaving the gas station S is ensured.
[0022]
【The invention's effect】
As described above, the display device of the present invention includes a first vehicle detector that detects a vehicle traveling on a road, a second vehicle detector that detects a vehicle exiting from an exit, an advertisement display, and an exit display. Display means for selectively displaying the vehicle and the stop display, and a control device for receiving a signal from the first and second vehicle detectors and outputting a display signal to the display means. Receives a car non-detection signal from the intelligent device and outputs an advertising display signal, and receives a car non-detection signal from the first car detector and a car detection signal from the second car detector and outputs a departure display signal. Since the vehicle detection signal is output in response to the vehicle detection signal of the first vehicle detector and the vehicle detection signal of the second vehicle detector, if there is a vehicle exiting from the exit, the safety of the exiting vehicle If there is no car to leave, there will be a promotional display on the car traveling on the road to enhance the function of the display device. It can be.
